It is nice to see BMW at least gave the 1M a little more in the tune over a standard N54. They obviously could have put out much more if they wanted to. 346 wheel horsepower in STD correction is pretty darn good for with an intake. That is basically M3 power right there. The car is rated at 335 crank so when a vehicle is putting out more to the wheels than it is rated at the motor that is definitely what we call underrated. This leads us to believe the reason the 1M did not get the DCT transmission is it would have stepped all over the M3's toes.
